Answer:

Part A: The car shoots out of the milk carton at a fast speed.

Part B: Potential Energy

Part C:

1. Gravitational Potential Energy

2. Motion Energy

3. It goes from Motion Energy/Kinetic Energy to Gravitational Potential Energy.

4. Motion Energy

Part D: It is a transfer of energy from the rubber band to the car.

Part E: The car stopped because of gravitation pull that is slowly making the car slow down and eventually stop. The energy is then converted to kinetic energy and heat energy.

Part F: I would think adding force would make the car move again. The type of energy it would have while moving would be: Motion Energy.

Have a great day! :D

The inclined plane in the figure above has two sections of equal length and different roughness. The dashed line shows where sec
saveliy_v [14]

The static friction exerted on the block by the incline is \mu _ s _1 Mgcos \ \theta.

The given parameters;

  • <em>mass of the block, = M</em>
  • <em>coefficient of static friction in section 1, = </em>\mu_s_1<em />
  • <em>angle of inclination of the plane, = θ</em>

<em />

The normal force on the block is calculated as follows;

Fₙ = Mgcosθ

The static friction exerted on the block by the incline is calculated as follows;

F_s = \mu_s F_n\\\\F_s = \mu _s_1(Mg cos\ \theta)\\\\F_s = \mu _s_1 Mgcos\ \theta

Thus, the static friction exerted on the block by the incline is \mu _ s _1 Mgcos \ \theta

Air friction damps a tuning fork so the amplitude decreases by 1/10 per second. Resonances] 10 Hz. what % chnge in frequency res
aleksandr82 [10.1K]

Answer:

The percentage change in frequency is 10%.

Explanation:

Given that,

Amplitude decreases by 1/10 per second.

Resonance = 10 Hz

We need to calculate the change in frequency

Using formula of change in frequency

\Delta f=\Delta A\times R

Put the value into the formula

\Delta f=\dfrac{1}{10}\times10

\Delta f=1\ Hz

We need to calculate the resonant frequency

Using formula of resonant frequency

f_{r}=R-\Delta f

Put the value into the formula

f_{r}=10-1

f_{r}=9\ Hz

We need to calculate the percentage change in frequency

Using formula of percentage change in frequency

f=\dfrac{10-9}{10}

f=10\%

Hence, The percentage change in frequency is 10%.
